Here, the plurality of cameras 120 - 1 , ..., 120 - n may be provided on one side of a housing of the display device 100 on which the display 110 is provided.

For example, as shown in FIGS. 1A and 1B , when the width of the display 110 is longer than the length, the plurality of cameras 120 - 1 , ..., 120 - n are relatively in the housing of the display 110 . It may be provided on a short longitudinal side.

However, this is only an example, and the plurality of cameras 120-1, ..., 120-n may be provided in the bezel area of the display 110. Even in this case, the plurality of cameras 120-1, 120-n. .., 120-n) may be provided in a bezel area of a relatively short vertical side.

Meanwhile, although it is illustrated that there are two cameras 120-1 and 120-2 in FIGS. 1A and 1B, this is an example, and it goes without saying that the display apparatus 100 may include two or more cameras.

However, hereinafter, for convenience of description, it is assumed that the display apparatus 100 includes two cameras 120 - 1 and 120 - 2 .

Meanwhile, the plurality of cameras 120 - 1 and 120 - 2 may be rotated. To this end, the display apparatus 100 may include a motor (not shown) for rotating each of the cameras 120 - 1 and 120 - 2 .

In addition, when each of the cameras 120 - 1 and 120 - 2 is rotated to the left or right, the photographing direction of each of the cameras 120 - 1 and 120 - 2 may be changed to the left or right than before the rotation.

Meanwhile, according to various embodiments of the present disclosure, the display apparatus 100 may control the camera according to the arrangement state of the display 110 , for example, whether the display 110 is arranged in a horizontal direction or a vertical direction. Let me explain in more detail.

2 is a block diagram illustrating a configuration of a display apparatus according to an embodiment of the present disclosure.

Referring to FIG. 2 , the display apparatus 100 may include a display 110 , a plurality of cameras 120 - 1 and 120 - 2 , and a processor 130 .

The display 110 may be mounted on the display apparatus 100 to be rotatable.

For example, the display 110 may be mounted on a stand 10 for setting the display apparatus 100 on the floor, and may be arranged in a horizontal or vertical direction. In addition, the display 110 arranged in the horizontal direction may be rotated in the vertical direction, and the display 110 arranged in the vertical direction may be rotated in the horizontal direction. To this end, the display apparatus 100 may include a motor (not shown) for rotating the display 110 .

Also, the display 110 may display various images. To this end, the display 210 may be implemented with various types of displays, such as a liquid crystal display (LCD), a light emitting diode (LED), an organic light emitting diode (OLED), and a quantum dot light emitting diode (QLED).

Each of the plurality of cameras 120 - 1 and 120 - 2 may capture an image. To this end, each of the cameras 120-1 and 120-2 may include an image sensor (not shown) and a lens (not shown).

Here, the plurality of cameras 120 - 1 and 120 - 2 may have different angles of view. For example, the plurality of cameras 120 - 1 and 120 - 2 use the first camera 120 - 1 which performs photographing using a general lens and a wide-angle (or ultra-wide-angle) lens having an angle of view greater than that of a general lens. to include a second camera 120 - 2 that performs photographing.

The processor 130 may control the overall operation of the display apparatus 100 . That is, the processor 130 may be electrically connected to the display 110 and the plurality of cameras 120 - 1 and 120 - 2 to control these components.

To this end, the processor 130 may include a central processing unit (CPU) or an application processor (AP), and may include one or more instructions stored in a memory (not shown) of the display apparatus 100 . Accordingly, one or more software programs stored in a memory (not shown) may be executed.

Specifically, when the display 110 is vertically arranged, the processor 130 may perform photographing by using one of the plurality of cameras 120 - 1 and 120 - 2 . In addition, the processor 130 may display the captured image on the display 110 .

For example, when an application for taking a picture or video is executed according to a user command in a state in which the display 110 is vertically arranged, or an application for a video call is executed, the processor 130 may include a plurality of Photographing may be performed using one of the cameras 120 - 1 and 120 - 2 .

In this case, the processor 130 may perform photographing using the first camera 120-1 that performs photographing using a general lens among the plurality of cameras 120-1 and 120-2.

Meanwhile, when a user command for horizontally rotating the vertically arranged display 110 is input, the processor 130 may horizontally rotate the display 110 .

Specifically, the processor 130 may drive a motor (not shown) for rotating the display 110 to rotate the display 110 from a vertical direction to a horizontal direction.

Here, the user command may be received from a remote controller for controlling the display apparatus 100 or may be input through a button provided on the display apparatus 100 .

Meanwhile, the processor 130 may rotate the display 110 in a horizontal direction according to a user command, and may stop photographing through the camera. That is, the processor 130 may stop shooting by the first camera 120 - 1 while the display 110 is vertically arranged.

In addition, the processor 130 may perform photographing using the second camera 120 - 2 .

Here, the second camera 120 - 2 may be a camera having a larger angle of view than the first camera 120 - 1 . That is, the second camera 120 - 2 may be a camera that performs photographing using a wide-angle (or ultra-wide-angle) lens having a larger angle of view than a general lens.

Specifically, the processor 130 performs photographing using the first camera 120-1 among the plurality of cameras 120-1 and 120-2 in a state in which the display 110 is vertically arranged, and the display When a user command for rotating the 110 in the horizontal direction is input, the display 110 is rotated in the horizontal direction, shooting through the first camera 120-1 is stopped, and the second camera 120-2 is You can take pictures through .

In addition, the processor 130 may display the image captured by the second camera 120 - 2 on the display 110 .

Accordingly, when the display 110 is arranged in a horizontal direction, an image captured by the second camera 120 - 2 may be displayed on the display 110 .

In this case, the processor 130 identifies an object included in the image photographed by the first camera 120-1 from the image photographed by the second camera 120-2, and the identified object moves in the horizontal direction. An image photographed using the second camera 120 - 2 may be displayed on the display 110 so as to be displayed on the central region of the arranged display 110 .

Specifically, the processor 130 may capture an image through the first camera 120 - 1 in a state in which the display 110 is vertically arranged, and may identify an object in the captured image. Here, the object may include a human face or the like.

Then, the processor 130 rotates the display 110 arranged in the vertical direction in the horizontal direction according to a user command, and stops shooting by the first camera 120-1 as the display 110 is rotated, An image may be captured through the second camera 120 - 2 .

In this case, the processor 130 identifies the same object as the object identified in the image captured by the first camera 120-1 from the image captured by the second camera 120-2, and the identified object is An image captured by the second camera 120 - 2 may be displayed on the display 110 arranged in a horizontal direction so as to be displayed on the central region of the display 110 arranged in the horizontal direction.

That is, the processor 130 detects a region including a human face in the image captured by the first camera 120-1 using a face detection algorithm, etc., and detects the eyes, nose, mouth, etc. in the detected region. It is possible to obtain characteristic data by analysis.

Then, the processor 130 detects a region including a face in the image captured by the second camera 120 - 2 , and analyzes the eyes, nose, mouth, etc. in the detected region to obtain feature data, and Comparing the feature data obtained from the image captured by the first camera 120-1, the face region in which the feature data matches (or matches) is determined from the image captured by the second camera 120-2 can do.

That is, the processor 130 may determine a region including the same face as the face identified in the image captured by the first camera 120 - 1 from the image captured by the second camera 120 - 2 . .

Then, the processor 130 controls the second camera 120-2 so that the region determined from the image captured by the second camera 120-2 is displayed on the central region of the display 110 arranged in the horizontal direction. The captured image may be displayed on the display 110 .

On the other hand, when a user command for rotating the horizontally arranged display 110 in the vertical direction is input, the processor 130 rotates the display 110 in the vertical direction, and uses the second camera 120 - 2 . You can stop shooting.

In this case, the processor 130 may capture an image through the first camera 120 - 1 , and display the captured image on the display 110 arranged in the vertical direction.

As described above, according to an embodiment of the present disclosure, the display apparatus 100 may change a camera that performs photographing according to the arrangement state of the display 110 . The reason is as follows.

Specifically, when the display 110 is rotated, the position at which the camera performs the photographing is changed. In this case, when the display 110 is rotated so that the user's appearance is constantly photographed, the user must change his or her position accordingly. and this may cause inconvenience to the user.

Accordingly, according to an embodiment of the present disclosure, when the display 110 is rotated in the horizontal direction while capturing an image through the first camera 120-1 in a state in which the display 110 is arranged in the vertical direction, An image may be captured by using the second camera 120-2 having a larger angle of view than the first camera 120-1 used for photographing in the vertical direction.

This is because when the display 110 is rotated from the vertical direction to the horizontal direction, the position of the camera is relatively changed to the left or right than when in the vertical direction. In this case, the photographing is performed using a camera having a relatively larger angle of view than in the vertical direction.

Then, the processor 130 detects a face detected in the image captured when the display 110 is in the vertical direction from the image captured when the display 110 is in the horizontal direction, and the region including the detected face is displayed in the horizontal direction. The captured image may be displayed on the display 110 arranged in a horizontal direction so as to be displayed on the central portion of the display 110 arranged as .

Accordingly, according to an embodiment of the present disclosure, even if the position at which the camera performs photographing is changed as the direction of the display 110 is changed, an image captured by the user is provided without causing inconvenience to the user be able to give

For example, as shown in FIG. 3A , in a state in which the display 110 is vertically arranged, the processor 130 uses the first camera 120-1 among the plurality of cameras 120-1 and 120-2. to capture an image, and display the captured image 310 on the display 110 .

In addition, when a user command for rotating the vertically arranged display 110 in the horizontal direction is input, the processor 130 may rotate the display 110 so that the display 110 is horizontally arranged.

In this case, as shown in FIG. 3B , the processor 130 stops shooting by the first camera 120 - 1 , takes an image using the second camera 120 - 2 , and captures the captured image 320 . may be displayed on the display 110 .

In this case, the processor 130 detects a face detected in the image 310 captured when the display 110 is in the vertical direction from the image captured when the display 110 is in the horizontal direction, and a region including the detected face The captured image may be displayed on the horizontally arranged display 110 so as to be displayed on the central portion of the horizontally arranged display 110 .

That is, referring to FIGS. 3A and 3B , when the display 110 is arranged in a horizontal direction, the display apparatus 100 may capture an image through a camera having a wider angle of view than when the display 110 is arranged in a vertical direction. Accordingly, when the display 110 is in the vertical direction, shooting starts, and thereafter, even if the display 110 is rotated in the horizontal direction, the user can provide an accurately captured image.

On the other hand, in the above example, when the display 110 is rotated in the horizontal direction, it has been described that the first camera 120-1 stops shooting and the second camera 120-2 performs the shooting. , this is only an example.

That is, in a state in which the display 110 is vertically arranged, the processor 130 may capture an image by using the first camera 120-1 among the plurality of cameras 120-1 and 120-2.

In this case, the processor 130 detects a region including a human face from the image captured by the first camera 120 - 1 in a state in which the display 110 is vertically arranged, and in the detected region Feature data may be obtained by analyzing eyes, nose, mouth, and the like.

In addition, when a user command for rotating the display 110 is input, the processor 130 may rotate the display 110 so that the display 110 is arranged in a horizontal direction.

In this case, the processor 130 may perform photographing through the first camera 120 - 1 even when the display 110 is arranged in the horizontal direction.

That is, the processor 130 may perform photographing through the first camera 120 - 1 without stopping the photographing through the first camera 120 - 1 , even after the display 110 is horizontally arranged. .

In addition, the processor 130 detects a region including a human face from the image captured by the first camera 120 - 1 in a state in which the display 110 is horizontally arranged, and in the detected region, the eyes , nose, mouth, etc. can be analyzed to obtain feature data.

In this case, the processor 130 determines that the feature data obtained from the image captured with the display 110 arranged in the horizontal direction and the feature data obtained from the image captured with the display 110 arranged in the new direction are If they match, shooting may be performed using the first camera 120 - 1 .

However, the processor 130 determines that the face region is not detected in the image photographed with the display 110 arranged in the horizontal direction, or features obtained from the image photographed with the display 110 arranged in the vertical direction. If data is not obtained from the image captured while the display 110 is horizontally arranged, the first camera 120-1 stops shooting, and the second camera 120-2 is used to capture the data. can be performed.

Meanwhile, according to an embodiment of the present disclosure, when the display apparatus 100 is set on the floor using the stand 10 , for example, as shown in FIG. 4 , the display apparatus 100 is tilted by a specific angle from the floor. It can be erected on the floor in a tucked state.

As such, when the display apparatus 100 is tilted, the camera accurately captures a user located in front of the display apparatus 100 in that the photographing direction 410 of the camera is directed upward by a predetermined angle with respect to the front surface. may not be able to

Accordingly, according to an embodiment of the present disclosure, the display apparatus 100 may identify a tilting angle at which the display 110 is inclined, and rotate the camera based on the identified tilting angle to capture an image. .

To this end, the display apparatus 100 may further include a sensor (not shown). Here, the sensor (not shown) may include at least one of an acceleration sensor, a tilt sensor, a gyro sensor, and a magnetic field sensor (3-axis magnetic sensor). In this case, the sensor (not shown) may transmit the sensed sensed data to the processor 130 .

For example, assuming that the sensor (not shown) is an acceleration sensor, the sensor (not shown) may measure the gravitational acceleration of each of the X-axis, Y-axis, and Z-axis with respect to the display 110 .

At this time, when the display device 100 is erected obliquely through the stand 10 , the display 110 mounted on the stand 10 is also obliquely disposed with respect to the floor, so that the measurement is performed by a sensor (not shown). ^{The resulting gravitational acceleration is measured as a value other than 0 m/sec 2} in at least one axis, where the square root of the sum of the squares of the components of the three axes, i.e., the magnitude of the vector sum, is a certain value (e.g., 9.8 m/sec ² ). can be In this way, the sensor (not shown) may detect the respective accelerations in the X-axis, Y-axis, and Z-axis directions in the coordinate system. In this case, it goes without saying that the respective axes and the corresponding gravitational acceleration may be changed according to the position where the sensor (not shown) is attached.

Meanwhile, the processor 130 may identify the tilting angle of the display 110 using the gravitational acceleration transmitted from a sensor (not shown).

Here, the tilting angle may mean an angle at which the display 110 is tilted with respect to a plane perpendicular to the floor on which the display apparatus 100 is erected.

In this case, the processor 130 may calculate a tilting angle (eg, θ of FIG. 4 ) of the display 110 by using the measured acceleration for each axis component transmitted from a sensor (not shown).

Meanwhile, in the above-described example, it has been described that the processor 130 determines the tilting angle of the display 110 using the acceleration sensor, but this is only an example, and sensing sensed by various sensors such as a tilt sensor, a gyro sensor, and a magnetic field sensor The tilting angle of the display 110 may be determined using the data.

In this way, the processor 130 may identify the tilting angle of the display 110 based on the sensed data received from the sensor (not shown).

Meanwhile, the processor 130 may identify a tilting angle of the display 110 based on sensing data received from a sensor (not shown) in a state in which the display 110 is vertically arranged.

In addition, the processor 130 may rotate the photographing angle of the camera based on the identified tilting angle. Here, the camera may include the first camera 120 - 1 .

Specifically, the processor 130 determines a tilting angle of the display 110 in a state in which the display 110 is arranged in the vertical direction, and operates a motor (not shown) for rotating the first camera 120-1. By driving, the photographing angle of the first camera 120 - 1 may be rotated downward by the tilting angle.

For example, as shown in FIG. 5A , in a state in which the display 110 is vertically arranged, it is assumed that _{the tilting angle of the display 110 is θ 1°.}

In this case, the processor 130 may rotate the photographing angle of the first camera 120-1 downward by _{θ 1°, as shown in FIG. 5B .} Here, the processor 130 may rotate the first camera 120 - 1 in the lower direction within the housing or the housing itself including the first camera 120 - 1 may rotate in the lower direction.

Accordingly, as shown in FIGS. 5A and 5B , the angle of view 520 of the first camera 120 - ₁ is higher than the angle of view 510 before the first camera 120 - 1 is rotated by θ 1°. Since it faces downward, the display apparatus 100 can more accurately photograph a user present in front of the display apparatus 100 .
